OSWALD S. PULLIAM, OF PITTSBURGH, AND JOHN ALLISON, OF DRAVOSBUBG, PENN- SYLVANIA, ASSIGNORS T0 PITTSBURGH EQUIPMENT COMPANY, OF PITTSBURGH, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.

SIDE-FRAME CONSTRUCTION.

To all whom it mafioncern Be it known that we, OswALD S. PULLIAM and JOHN ALLISON, respectively of Pittsburgh and Dravosbur in the county of Allegheny and State 0% Pennsylvania, have invented certain new and useful Improvements in Side-Frame Construction, of which the following is a specification.

The object of our invention is to provide a new and improved side-frame construction, and to this end our invention consists of a side-frame, in the novel features of construction, and in the combination of parts all as fully herein described and claimed.

In the accompanying drawings, which illustrate applications of our invention, Figure 1 is a perspective view of a side-frame proper and journal-boxes embodying our invention; Fig. 2 a part elevational and a art sectional view of an end of the form of ig. 1; Fig. 3 a perspective view of a journalbox; Fig. 4 a part side elevational and a part sectlonal view showing a modified form of our invention; Fig. 5 a part plan and a part sectional view, the section being taken on line 5-5 of Fig. 4:; Figs. 6 and 7 detail plans showing tie-bars in engagement with lugs on the lower-member of side-frame proper; Fig. 8 a part elevational and a part sectional view, the section being taken on line 88 of Fig. 4; and Fig. 9 a perspective view of filler employed.

Referring to the drawings, and first to the form of Fig. 1, the side-frame construction therein illustrated comprises the side-frame proper and the journal-boxes secured thereto. The side-frame comprises a top-member 1, a bottom-member 2, web-portions 3 connecting the top and bottom-members, a spring-seat 4 and end-members or plates 5. All of the elements above mentioned, as illustrated and as referred are made in an integral cast meta structure and the endmembers or lates 5 which are formed on the top mem er of the side frame are de signed to be employed' for the lids or tops of the journal boxes. In this form the top and bottom-members are of channel-form and are arranged with their side flanges extending in opposite directions or toward each other.

The top-member 1 has formed integral therewith, push-pockets 6, and the bottommember is formed with lugs 7, adapted to engage a tie-bar 8. The tie-bar 8 and the en- Specification of Letters Patent.

- its column-guides 11, as shown by Fig. 4.

12 designate journal-boxes each formed w th an opening 13 therein. In the form of Fig. 1 the journal-boxes are provided with arms 14 adapted to be connected with the bottom-member of the side-frame and with an engaging-flange 15 which latter fits into a receiving-groove 16 ot' the plate-member 5. When the journal-boxes are secured to the ends of the side-frame the plates or members 5 extend over the upper portion of the journal-boxes and serve as tops for the boxes.

In place of having a separate journal-box wedge, this wedge, under our construction, may be formed integral with the plate-member 5. In Fig. 2, we have shown the wedge 17 as part of the said member with the wedge in contact with the brass bearing 18. In the form of Fig. l we have shown our invention in connection with the bolster 1O andsprmgs 18 in place in the bolstenreceivmg-opening. In this form, the journalboxes are secured to theend of the sideframe in a different manner than that of the form of Fig. 1 and the opening 13 of the journal-box is made smaller than the opening of the first form. In this form the boxes are each formed with spaced lugs 19 adapted to engage members 20 of the side-frame and the plate-member 5 is secured to the respec tive boxes by bolts 21.

Attention is called to the contraction of the width of the bolster between its columnguides or to the cut-in or recessed portions into which the arms 23 of the filler fit. In

this construction we show the wedge 17 H CID,

bination with a bolster having columnguides formed integral therewith, of a side frame formed with bolster-guides and a bolster receiving opening, said column-guides a being projected to engage the bolsterguides,

and a filler interposed between the bolsterguide and the bolster.

2. In a side-frame construction, the combination with a bolster having columnguides formed integral therewith and a recess adj acentto the column-guides, of a side frame formed with bolster-guides and a bolster receiving opening, said column-guides being projected to engage the bolster-guides, i5 and a filler located in the recess of the bolster and between the bolster-guide and bolster.

8, In a side-frame construction the combination with a bolster having column-guides formed integral therewith and a recess adj acent to the column guides of a side-frame comprising a top-member formed with a journal-box lid and a bottom-member, said frame formed with a bolster-receivingopening of substantially the same width throughout its length and with the width of the opening less than the width of the bolster measured over its column-guides, and a filler-member located in the recess of the bolster 4. In a side-frame construction, the combination with a bolster having columnguides formed integral. therewith, and with a recess on each side face, of a side-frame comprising a top-member having journal box lids formed integral therewith, a bottom member, said frame having a bolster-receiving opening of substantially the same width throughout its length and with the width of the opening-less than the width of the bol- 40 ster measured over its column-guides, and a filler having upwardly extending-members located in the recesses of the bolster.

5. In a side-frame construction the combination with a side-frame proper formed with a bolster-receiving opening of substantially the same width throughout its length and with the width of the opening less than the width of the bolster measured over its column-guides, of a bolster located in the.

opening having column guides and formed with a recess on each side thereof, bolster springs, and a filler having upwardly extending members, said filler interposed between the springs and the bolster and having its upwardly extending members located in the recesses of the bolster.

6. A side-frame comprising a topmember of channel form having push-pockets formed integral therewith.

7. The combination with a journal-box open at its top and provided with an outwardly projecting-arm, of a side-frame having a top-member formed with a top for the 8. In a car truck, side frames having columns, a bolster spaced away from the inner faces of said columns, column guides which cooperate with said columns, said column guides being formed integral with the bolster, and removable fillers interposed between said bolsters and columns; substan tially as described. I

9. In a car truck, side frames having columns, a bolster spaced away from theinner faces of said columns, column guides which cooperate with said columns, said column guides being rigidly secured to the bolster,

and removable fillers interposed between said bolster and columns; substantially as described.

10. A car truck having side frames including columns, a bolster provided with column guides which cooperate with said columns, said bolster being spaced away from the inner face of the columns, and re movable fillers interposed between said bolster and columns; substantially as described.

' 11. In a car truck, side frames having columns, a bolster spaced away from the inner faces of said columns, column guides which cooperate with said columns, said column guides being formed integral with the bolster, and removable fillers loosely mounted between said bolster and columns; substantially as described.

12. A car truck having a side frame including columns and a spring seat, a spring on said spring seat, a bolster mounted on said spring and provided with column guides which cooperate with said columns, said bolster being arranged between said columns and spaced away from the inner faces thereof, and removable fillers interposed between said bolster and columns; substantially as described.

13. In a car truck, side frames having columns and a spring seat, a bolster having pairs of column guides which cooperate with said columns, removable fillers interposed between said bolster and columns, each of said fillers being arranged between a pair of said column guides, and springs interposed between said bolster and spring seat; substantially as described.

In testimony whereof We afiix our signatures in presence of two witnesses.
